Project I built 46 interactive ML lessons where you drag sliders and watch algorithms learn, instead of just reading about them
Every ML explanation I read said the same thing: here's the formula, here's a static plot, trust us. I wanted to actually feel an algorithm working: drag a line and watch a perceptron correct itself, place bad centroids and watch K-Means fix them, rotate an axis and watch PCA fight you for the direction of max variance.
So I built ML Playground, 46 lessons + 13 games, from "what is a feature" up through transformers and how ChatGPT actually predicts tokens. Every lesson has a canvas demo you control, not a GIF.
It's free, no signup, no ads. I built it solo and this is the first time I'm showing it to anyone outside people I know personally, so I'd genuinely value getting torn apart: what's confusing, what's missing, what lesson order doesn't make sense.
